Certificação ambiental e internacionalização: uma análise do setor madeireiro brasileiro

Abstract: A presente pesquisa analisa a influencia da certificacao ambiental sobre a internacionalizacao do setor madeireiro no Brasil. O estudo se desdobra em duas partes. Inicialmente, por meio de dados da FAO e do MDIC, foi calculada a Vantagem Comparativa Revela para os bens madeireiros. Esse indice mostrou que o Brasil, embora detenha imensas quantidades de recursos naturais, nao apresenta vantagem comparativa nesse setor. E com dados da Receita Federal Brasileira e do Forest Stewardship Council (FSC), que e o selo mais difundido no setor florestal brasileiro, foi possivel verificar que as empresas madeireiras certificadas exportam, em media, um valor maior que as nao certificadas e exportam tambem para um numero maior de paises. Os resultados encontrados aqui mostram a importância da certificacao ambiental tanto ao meio ambiente quanto as empresas.

Effects of two programs of metabolic resistance training on strength and hypertrophy

Abstract: Introduction: The effects of low intensity resistance training combined with vascular occlusion have been investigated by several studies. Similar results on strength and hypertrophy have been observed when such method was compared to high intensity protocols. However, due to the specific apparatus needed to apply vascular occlusion (ex.: Kaatsu) on some exercises, alternative forms of metabolic training might be used. In the present study, an isometric contraction was performed within each concentric-eccentric transition phase, for every repetition, to elicit metabolic stress. Objective: The aim of the present study was to analyze the effects of two resistance training protocols with metabolic characteristics on strength (1MR), circumference (CIRC) and muscle thickness (measured with ultrasonography [MT]). Subjective perception of discomfort was also recorded with an analogical-visual pain scale (AVP). Methods: Twelve young, healthy men were trained with two different methods during 10 weeks. The right limb was trained with an isometric contraction within each concentric-eccentric transition phases for every repetition (ISO) whereas the left limb was trained with a pneumatic cuff to apply vascular occlusion (OC) on the knee extensor muscles. Both methods were trained at 20% 1MR. Results: It was observed increases on medial tight CIRC, proximal MT, medial MT, distal MT and 1MR, with no difference between both methods. The perception of discomfort was greater for ISO at the end of the third set and lower than reported by OC, at the beginning and end of the training program. Conclusions: Both protocols produced similar gains on strength and hypertrophy. The advantages of training with low loads are important to elderly or rehabilitation training programs. Other studies that compare this method with conventional resistance training are warranted.

Case for diagnosis. Lichen myxedematosus

Abstract: Scleromyxedema or lichen myxedematosus is a rare papular mucinosis of chronic and progressive course and unknown etiology. It is commonly associated with monoclonal gammopathy and may show extracutaneous manifestations, affecting the heart, lung, kidney, and nerves. The diagnosis is based on four criteria: generalized papular and sclerodermoid lesions; mucin deposition, fibroblast proliferation, and fibrosis in the histopathology; monoclonal gammopathy; and no thyroid disorders. This article reports the case of a scleromyxedema patient with a recent history of acute myocardial infarction and monoclonal gammopathy.

Evaluation of surgical training in medical school

Abstract: OBJETIVO: Avaliar a efetividade de um treinamento de tecnicas cirurgicas em pata de porco durante a graduacao em medicina. METODOS: Estudo transversal com 87 academicos de medicina voluntarios, provenientes de diferentes periodos da graduacao, que participaram de uma oficina basica para realizacao de incisoes, suturas, biopsias, retalhos, enxertos, sob supervisao direta. Foram utilizados questionarios autoaplicaveis pre e pos-treinamento. RESULTADOS: O ensino de suturas, biopsias e correcao de orelha mostrou-se efetivo para o aprendizado de habilidades minimas exigidas para as tecnicas propostas (p 0,97). CONCLUSAO: A abordagem metodologica e o monitoramento de reproducao das tecnicas mostraram-se adequados. O treinamento oferecido complementou as habilidades cirurgicas cutâneas dos graduandos de medicina.

Para além do olhar econômico nas alianças estratégicas: implicações sociológicas do caso Unihotéis

Abstract: The purpose of this paper is to discuss the phenomenon of strategic alliances through a sociological perspective as a counterpoint to prevailing economic view, which privileges a conception of rational actor in a utilitarian and contrac-tual basis. The case study investigates the process of constitution of a strategic alliance in the hotel industry in Brazil. Interviews and documentary data were analyzed qualitatively through traditional content analysis and oral history tech-nique. The results revealed relevant emergent sociological aspects concerning strategic alliances which formed the basis for the establishment of four analytical propositions: 1. the process of constituting strategic alliances is influenced by the activity of different interested actors distributed in the political arena, whose actions are guided not only by utilitarian expectations, but also symbolic; 2. the effort of incumbent actors to justify and legitimize a project of interorganizatio-nal cooperation and to mobilize other actors in favor of ideas and interests that are consistent with this project influences the process of constituting strategic alliances; 3. principles, categories and shared understandings of interorganiza-tional cooperation, built on the interaction of the constituent actors with external agents, determine the formal and relational arrangements in the process of cons-tituting strategic alliances; 4. the constitution of strategic alliances depends on how organizational actors interpret their membership as desirable or obligatory in a given social context. We conclude in favor to a complementary approach between economic perspective and sociological view in strategic alliance studies, which recognize the social embeddedness of the economic actors as well as the relevance of the institutional dimension of organizational environment. In doing so, we believe the economic approach will benefit from a more complex and comprehensive understanding of strategic alliances.
